GEORGE K. I'IUBBARD, OF FORT 1WAYNE, INDIANA.

SPECIFICATION forming part of Letters Patent No. 430,475, dated June 17, 1890.

Application filed January 20, 1890- Serial No. 337,563. (No model.) I

T all whom, t may concern:

Be it known that I, GEORGE K. IIUBBARD, a citizen of the United States, residing at Fort NVayne, in the county of Allen and State of Indiana, have invented a new and usefulSection-Press, of which the following` is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to improvements in machines used for puttingtogether small frames or boxes, known as sections, used tor comb.

honey and other purposes where a light strong box is desired; and the objects of my improvement are to provide a press that will put sections together firmly with great rapidity and without danger of their being broken or left askew when finished. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure lv is a vertical section of the entire machine;` Fig. 2, a perspective view of the entire machine, and Fig. 3 a perspective View of the section to be pressed together in the form of a frame or box.

Similar letters refer to similar parts throughout the several views.

The letter C represents the back of the machine, being the part to which the rest ot' the machine is built.

A and B are two movable arms, so hinged at L and K, respectively, as to permit their inner ends being pushed together until they are parallel with the back C.

D is a bloek affixed to the arm B, which has a large right-angled not-ch in its upper edge. This notch is of proper size to admit the section P, and thus iirmly supports the two lower sides of the section when pressure is applied to the dovetailing R by the block E, to be hereinafter described.

E is a block attixed to and projecting beyond the lower end et' arm A, containing in its lower edge a notch similar to but much smaller than the notch in D. The blocks D and E are so placed on the arms B and A that their respective notches are exactly opposite to each other.

G is a U-shaped spring ailixed to the back C and presses outward against the arm B to give rigidity to the arm l5 while placing the section P into the large notch in block l).

I is a hook, which engages the spring G whenever the arm B has been moved outward far enough to easily admit the section P between the large notch in block D and the smaller notch in block E.

F isa small piece which extends beyond the lower end of and is affixed to the under side of arm A. The piece F and block E, projecting, as they both do, beyond the lower end of arm A, form an aperture or slot, in which the upper end of arm B moves, thus compelling the arms A and B to work in unison.

I-I is a small block of rubber attached to the back O, serving as a stop for the arm B when the arms A and B, working in unison, have been brought into a position parallel with the back C.

N represents a rod attached near the upper end of arm B and pivoted tothe wheel O, showing how the machine can be easily connected with and operated by any other kind of power than by hand-pressure.

M is aslot in the metal plate L, allowing a slight variation in the adjustment of the arm A, whereby the pressure upon the section at AR maybe increased or diminished when said section is properly placed in the press, as hereinafter described. The kind ot' section most generally used is illustrated in Fig. 3. Itis made of a single strip of wood, dovetailed at each end, and so grooved erosswise at three equidistant places as to permit its being folded together in the form ot a box, as shown at P. Another kind quite generally 4used is made of four pieces and is dovetailed at each corner. My section-press is adapted to putting together either of these kinds of sections. In putting together the one-piece section one pressure only is required to each section,the pressure to be applied at the dovetailed corner. .In putting together the four-piece section each section must be pressed four timesonce at each corner. By placing the section in the large notch in block D, Wit-h the corner uppermost which it is desi red to press together, a slight push forward will cause the arms A and B to assume the position of a straight line, thus bringing the blocks E and D closer together, and thereby amassing at the single point within the small notch in block E all IOO the power to be gained by such a togglej'oint pressure, thus easily and securely forcing,` together the dovetailing shown at R.

I am aware that prior to my inventionla section-press has been made whereby pressure is applied to one corner of the section by means ot' a lever to be operated by hand. Both hands have to be used to get a section in position to press, and with my machine the very instant that a section is properly placed a slight push forward forces the dovetailing together. No time is lost by making' such a change that one hand may hold what both hands have put in position While the other hand grasps a lever and operates it; but even before the section is nally placed the motion can be commenced that will put the section together.

Havingthus described my invention and set forth its advantages, I claim as new and desire to secure by Letters Patent- The combination, with the back C, of the plates K and L, secured to opposite ends of the back and one adjustable thereon, the arm A, pivoted at one end to the plate L and at z the other end provided with a notched plate E upon one side and a lug;` F on the other beneath the notch in the plate E, the arm B, pivoted at one end to the plate K and at the other carrying a notched plate D at a dis- 3 tance from the end of the arm, the elastic stop II on the back beneath the arm B, the U-shaped spring G, secured at one end to the back, with coils near its attachment to the back, and the hook I on the underside of the 3 arm B, near its free end, substal'itially as and for the purpose speciied.

GEORGE K. IIUBBARD.
